i have just recently purchased a SeaGate 1TB External Hardrive. i have very sensitive information on this storage unit that i only want certain people to have access to. is there any way of password protecting the hardrive? preferably using linux or what are my options?
View 9 RepliesI have recently bought a new laptop, installed my first linux OS on it (Ubuntu 9.10) and an external hard drive with 500GB on it for backup. For the first few days my external hard drive was working fine, but then eventually it wouldn't let me copy/move/delete stuff to and from it. So I kept trying to change the permissions but it wouldn't let me.
I figured this would be a very very common problem, so I looked up some forums to try out the methods but they didn't work. So I thought I would ask you guys for help because I am pleased with the support. I wouldn't think this would be a hard problem to solve.
I have an external hard drive that has all of my Apple Powerbook G4 files on it. I plugged in my "Journal Extended" external hard drive into my new HP laptop with Ubuntu 10.10 on it.
All of my files are on the hard drive still, however lots of them have a little X on the folders and when I try to open them it tells me I don't have permission? How can I force the permission for everything on my external? It's my own files and I can't even access them lol.
I have an OpenBSD and a FreeBSD system and a mac. I also have a Ubuntu server. What i would like to do is back up all these systems to an external hard-drive using rsync when the external usb disk is connected to my Ubuntu box.If i format the external usb disk with cfdisk and the create a non-bootable ext3 file system on this external disk and create and put all the necessary public keys on the Linux box then from the BSD's or the mac issue the command:
Code: #rsync --progress -avhe ssh --delete / user@ubuntuBox:/usb/disk/path/dir/ Will this back up the entire systems so that they can be restored in the event of an emergency? I should store each OS just in a separate disk file of the external usb drive each time right?? Because i would rather not have to format the external usb drive for each different OS. Would this work? and would the restoration command for these BSD's be:
Code:
rsync -avze ssh UbuntuBox:/usb/disk/path / I just need to know the basics. I'm sure given that i'll be able to automate the process. I don't want to clone the disks for forensics. I just want to have a way of restoring to a clean OS. This is the most basic question:All the howto's never mention whether or not you have to have an rsync server running on the machine your backing up to. So do you just push or pull from one end of the connection only or do you have to have a client at one end and a server at the other, as is traditional?
I've been running Linux for a year on our family computers (one desktop, one laptop and two netbooks). I've run into a problem with the encrypted ext4 partition (270GB) on a LaCie external hard drive which also has a NTFS partition (50GB) which is not encrypted . First two times I tried using the encrypted ext4 partition (from two different computers) it worked fine but now I can't access it at all. I can still access the NTFS partition.Encrypted external hard drive partition will unlock but won't mount (or unmount). The computer says "Opening 320GB Hard Disk" but after a minute says, "Unable to mount location. DBus error org.freedesktop.DBus.Error.NoReply"Disk utility (GUI for gparted I believe) states that the encrypted partition (/dev/sdb1) is unlocked and the underlying partition (/dev/dm-0) is not mounted but it has a "busy circle sign" on it that will not turn off. The NTFS partition on the same drive mounts and accesses normally.
But if I try to unmount the NTFS partition, it says: "Unable to stop drive. One or more partitions are busy on /dev/sdb"If I try to shut down the computer, it is unable to shut down because (I assume) it can't shut down that drive either. So I have to just turn off the computer.fdisk states that /dev/dm-0 doesn't have a valid partition table [full output attached]fsck suggests: "Filesystem mounted or opened exclusively by another program?"ps axuf shows some processes running on /dev/dm-0 but killinghem doesn't release the drive either. [full output attached]I checked /etc/blkid.tab (suggested in one vaguely related thread) and there's no actual file only a broken link pointing to /dev/.blkid.tab (which doesn't exist). I tried deleting this link and rebooting but that didn't change anything.when I finally gave up my data as lost, I tried to format the partition (using Disk Utility) and it refused saying, "One or more block devices are holding /dev/sdb"
now I'm done full transition from windows 100%.i want ask how can i check my memory stick and External Hard Drive from virus ?

I've been struggling with the problem of scanning an external drive that is used to store the backup from a Windows 7 machine. The Windows 7 machine was infected but the user continued to backup to the external drive. He has since formatted his machine and reinstalled Windows 7, but now he would like restore whatever he can from the backup on the external drive. I've been attempting to scan the external drive for viruses using ClamTK by connecting it to my laptop running Ubuntu 10.04, but it has not worked. There is supposed to be about 10 gigs of backed up data, but I haven't seen any. I don't know why it is not mounted.
View 5 Replies View RelatedSo what I want to do is encrypt my entire hard drive, but heres the thing.
I dual boot Ubuntu and windows 7, but I am afraid that if I use truecrypt to do the encrypting that it will wipe GRUB and not allow me to boot into any OS, is that a possibility and is there a way around it?
I have a friend that has a computer running UBUNTU he has not used in a while and has forgotten the user name and password for it. Is there away to retrieve the data from this hard drive?
View 2 Replies View RelatedI'm installing fedora 12 on a laptop using the live cd, and I have a few questions about the encryption process.
First, I'd like to fill the drive with random data. I've read the fedora documentation and it suggests using the following command: dd if=/dev/urandom of=<device>. The installer didn't offer an opportunity to do this, so I opened a terminal and typed the command. I expected it to take hours on my 160 gig hard drive, but it only took about 3 minutes, and indicated about 600 megs of data had been written. Did I do it correctly? According to palimpsest, my boot partition is sda1 and the other partition is sda2, so that's the one ran the command with.
Second, I need some advice on what to encrypt. The installer shows me the following layout after I select encryption:
LVM Volume Groups
Hard Drives
I know I can't encrypt boot, but I can encrypt lv_root and lv_swap. But is it necessary to do that? And tell me the pros and cons of using a boot loader password?
I encrypted my hard drive on my media PC but it's really annoying having to type in a password every time I turn it on. I chose a short password so it was quick and easy to type in but is it worth encrypting data with a weak password?If the computer is suspended, someone could come along and resume the computer. They would be presented with a locked GNOME session) but the data would be unencrypted; does this go against encrypting the hard drive? Or does the locked GNOME session provide enough security to keep an intruder out?
View 9 Replies View RelatedWhat I want to do is pull data from any of the hard drives attached to my Linux box from my Windows machine. I have been moving small amounts of data from the drives to my OS drive and those parts share easily, but I want to move away from that method to move large amounts of data at the same time.I have tried using Samba as it is used for file sharing between systems and that I have to give my Windows box permission through Samba.
Trick is, I'm not sure where to start, though I have an idea and wanted to know if this is the right track before I start editing my file system.
I want to access my hard drive to copy over my old documents. So I boot into a LiveUSB, mount my ubuntu partition, and then cd to my home directory, but I can't open it. I get "permission denied." I encrypted my whole home directory and know the password, but how do I "decrypt" it or login as the partition's root so I can access the documents that way. I'm booted into the USB, but can't access the home directory. I get "You do not have the permissions necessary to view the contents of 'jake'".

View 1 Replies View RelatedI am surprised (from the searches I carried out on the net) that no one seems to have considered this danger so far as I can see...I'm a little concerned about the implications on security for algorithms that opaquely shift data blocks around on disks to even-out surface wear rates.In the good old days, if I wanted to wipe a file that documented my struggle to give up frosted strawberry donuts (for example) I knew where that file started on the disk and how long it was and could thus instruct the OS to wipe it with complete confidence.
Nowadays, however, with increasingly sophisticated use being made of W-L techniques and fancy, journaling file systems that separate meta-data from file content and whatnot and so forth, how can I still be sure that when I try to overwrite a personal and private file, that i AM actually doing precisely THAT, and not just nuking some virtual image of the thing which in reality remains preserved elsewhere on the disk?
I want to view a hard drive and see if it has all zeroes, how would I do this? I want to view a hard drive and see if it has all random data, or random data mixed with zeroes. How can I do this? I prefer to do all this in linux if possible without a gui...so looking for any cli tools to view with.
View 5 Replies View RelatedSince August of 2009 I have been under attack by corporate Black Hats. I found a 105GB FAT16 Hidden partition on my hard drive. Seventy four percent full (78GB). What led me to this was the fact that I couldn't help but notice that my Internet connection was a revolving door that never stopped spinning. So I went looking for why.
I removed the hidden flag, and patched the partition, but couldn't open that thing no matter what I did. I tried for a month. The attacks started as soon as I stopped these guys from accessing that data. At this point we are 9 months into 24/7 attacks. I have interviewed with the FBI, and local law enforcement, but they are intent on making me out to be a conspiracy nut. I am not at all. All they wanted to do is quiz me on my computer skills. If I managed to draw the attention of a corporate security group they killed it.

View 6 Replies View RelatedI have a 500 gb external hard drive with tons of personal files on it. Other people at home just grab my hard drive whenever they need to transfer files. I feel so disrespected. I also want to protect myself from actually losing my hard drive to a stranger who will compromise my data.
I'm thinking of encrypting, but I'm currently too busy to explore (the options seem to be hard to use) and it seems to be too much to encrypt a 500gb hard drive
What are my options in "locking" my hard drive. I don't mind if it's going to be readable only on Ubuntu. That could actually be a plus

I would like to install Linux Ubuntu 11.04 on an external hard drive - its partitioned and ready for Linux.I've downloaded and burnt the .iso file to a DVD so its all good so far...First of all... is this possible without messing up my macbook? I don't particularly want to break into my macbook to disconnect the hard drive (I read on a tutorial for a previous version of Ubuntu that I'd have to do that... - does it still apply to 11.04?) - as it voids the warranty (I checked ).The reason I ask this is because I had a friend who partitioned their internal hard drive and installed Ubuntu on it. But after installation was complete they couldn't boot up Windows 7 or Ubuntu... and it resulted in them having to clean install Windows 7... - I don't want to end up in that situation
Second... If it is possible to install it without messing up my macbook... - Do I just follow the install instructions but just make sure that where possible I make sure that everything is installed on my external hard drive?...I really need someone to put my mind at rest that everything will run smoothly and that I'll be able to run Mac OS X as usual but also that I'll be able to boot from my external hard drive to run Ubuntu.
